REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 62/287,270 filed Jan. 26, 2016, entitled “SNAP-LOCK CONSTRUCTION TOY”, the contents of which are herein incorporated by reference in their entirety.

FIELD

The present disclosure relates generally to construction sets, and more particularly to construction toys with multiple shaped components removably connectable with male and female connectors.

BACKGROUND

Construction toys have been developed over the years for play, education, and industry modeling. In particular, various injection molded construction toy building blocks have been introduced, where individual blocks are stacked atop one another to form various creations.

Conventional construction toys have components that are three dimensional, however they are limited in their angular orientation, as well as being limited in angled connection of components. Further, male and female connector portions are generally smooth and are held together with friction, resulting in reduced stability and ultimately abrasive wear on components.

Various others have attempted to overcome some of the limitations of such designs with various levels of success. There continues to be a need for multi-functional construction toys with multi-faceted and multi-angular connectable components. There also continues to be a need for reusable connector portions that lock into position and provide greater stability while being simple to use.

SUMMARY

The present disclosure provides a construction toy that utilizes snap-lock technology in an innovative manner. Accordingly, the following presents a simplified summary of the disclosure in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the invention. It is intended to neither identify key or critical elements of the invention nor delineate the scope of the invention. Its purpose is to present some concepts of the invention in a simplified form as a prelude to the more detailed description that is presented later.

In accordance with one aspect of the disclosure, a snap-lock toy is provided, wherein the snap-lock toy comprises a body having at least a first end disposed along an axis thereof. In accordance with one example, a female snap-lock connector is provided and has a generally hollow interior extending into the first end of the body. The female snap-lock connector, for example, comprises a bifurcated engagement member configured to receive a male snap-lock connector along the axis of the body. The male snap-lock connector, for example, has a head, a neck, and a shoulder.

The bifurcated engagement member, for example, comprises a first female engagement member and a second female engagement member separated by a slit. Each of the first female engagement member and second female engagement member, for example, each respectively comprise a wall having a head engagement region, a neck engagement region, and shoulder engagement region. The first female engagement member and second female engagement member, for example, are configured to elastically deflect from respective original states upon receiving the head and neck of the male snap-lock connector. Further, in another example, the first female engagement member and second female engagement member are configured to return approximately to their respective original states once the head of male snap-lock connector is lodged within the head engagement region of female snap-lock connector.

In one example, the head and neck of the male snap-lock connector are mushroom-shaped. For example, a shape of the shoulder of the male snap-lock connector and shoulder engagement region of the female snap-lock connector are complementary in shape when viewed along the axis. In another example, the shoulder engagement region of the female snap-lock connector is larger than the shoulder of the male snap-lock connector when viewed along the axis.

In still another example, the shoulder engagement region of the female snap-lock connector is generally octagonal in shape. As such, for example, the shoulder engagement region of the female snap-lock connector generally provides a plurality of 45 degree increments of insertion of the male snap-lock connector.

According to another example, the shape of the shoulder of the male snap-lock connector and shoulder engagement region of the female snap-lock connector generally maintains a rotational orientation of the male snap-lock connector with respect to female snap-lock connector. The body and female snap-lock connector, for example, are comprised of a plastic. The body may further comprise one or more stiffening members configured to stiffen the body.

In another example, the first female engagement member and a second female engagement member are mirror images of one another when viewed along the axis. One or more ribs may be further defined in the body, wherein the one or more ribs support the first female engagement member and second female engagement member. For example, the slit and the one or more ribs are configured to enable the first female engagement member and second female engagement member to elastically deflect as the head of the male snap-lock connector is pushed through the neck engagement region.

Another example includes a plurality of female snap-lock connectors extending into a plurality of ends of the body. In another example, another male snap-lock connector is disposed at a second end of the body, wherein the male snap-lock connector has another head, another neck, and another shoulder.

In still another example, the first female engagement member and second female engagement member return to their respective original states once the head of male snap-lock connector is lodged within the head engagement region of female snap-lock connector selectively secures the male snap-lock connector to the body.

In accordance with another exemplary aspect, a snap-lock toy is provided having a body with a first end and a second end, wherein the first end has a first axis associated therewith. A female snap-lock connector has a generally hollow interior extending into the first end of the body, wherein the female snap-lock connector comprises a bifurcated engagement member. The bifurcated engagement member comprises a first female engagement member and a second female engagement member separated by a slit. Each of the first female engagement member and a second female engagement member respectively comprise a wall having a head engagement region, a neck engagement region, and shoulder engagement region. The first female engagement member and second female engagement member, for example, are configured to elastically deflect from and to respective original states. Further, a male snap-lock connector extends from the second end of the body, wherein the male snap-lock connector having a head, a neck, and a shoulder.

In another example, the first female engagement member and second female engagement member are configured to elastically deflect from their respective original states upon receiving another head, another neck and another shoulder of another male snap-lock connector. The first female engagement member and second female engagement member are configured to return their respective original states once the another head of the another male snap-lock connector is lodged within the head engagement region of female snap-lock connector, therein selectively securing the another male snap-lock connector to the body.

In another example, one or more ribs are defined in the body, wherein the one or more ribs support the first female engagement member and second female engagement member. The slit and the one or more ribs, for example, are configured to enable the first female engagement member and second female engagement member to elastically deflect as the head of the male snap-lock connector is pushed through the neck engagement region.

In another example, the head and neck of the male snap-lock connector are mushroom-shaped, and wherein the shoulder of the male snap-lock connector and shoulder engagement region of the female snap-lock connector are generally octagonal in shape.

In accordance with another exemplary aspect of the disclosure, a snap-lock block is provided having a body with a first end and a second end disposed along an axis thereof. The body of the snap-lock block comprises a pair of cantilevered receptor wings disposed about the axis and extending approximately from the first end to the second end. The pair of cantilevered receptor wings, for example, are cantilevered from a leverage point associated with the first end and extend toward the second end.

A first female receptor, for example, is defined in the first end of the body of the snap-lock block, wherein the first female receptor has a first snap diameter defined between the pair of cantilevered wings. A second female receptor, for example, is defined in the second end of the body of the snap-lock block. The second female receptor, for example, has a second snap diameter defined between the pair of cantilevered wings, wherein the second diameter differs from the first diameter. A first predetermined moment, for example, is associated with the first female receptor. A second predetermined moment, for example, is associated with the second female receptor, whereby the first predetermined moment and second predetermined moment are defined based on a predetermined insertion force associated with an insertion of a male snap-lock connector into the first female receptor and second female receptor.

In one example, the first predetermined moment is based, at least in part, on the first snap diameter, and the second predetermined moment is based, at least in part, on the second snap diameter. The predetermined insertion force, for example, is approximately equal for an insertion of the male snap-lock connector into both of the first female receptor and second female receptor.

The first predetermined moment and second predetermined moment, for example, are further based on a respective first distance from the leverage point to the first snap diameter and a second distance from the leverage point to the second snap diameter. In another example, the first predetermined moment and second predetermined moment are further based on a material composition of the pair of cantilevered receptor wings. For example, the pair of cantilevered receptor wings are comprised of a plastic and are generally elastic.

In accordance with another exemplary aspect, an octagonal male feature extends outwardly a first predetermined distance from a surface associated with the first end of the body of the snap-lock block. Further, a generally square feature extends inwardly a second predetermined distance from the second end of the body of the snap-lock block. The octagonal male feature and generally square feature, for example, are sized such that generally square feature overlaps the octagonal male feature when viewed along the axis.

In one example, the first female receptor is generally centered inside the octagonal male feature. In another example, the octagonal male feature and generally square feature are configured to provide a friction fit between another octagonal male feature and another generally square feature of another snap-lock toy. The another octagonal male feature, for example, is dimensioned the same as the octagonal male feature and the another generally square feature is dimensioned the same as the generally square feature.

In another example, the octagonal male feature and the first female receptor are configured to mate with a snap-lock rod having a generally square body and the male snap-lock connector. An interface between the octagonal male feature and the square body, for example, provides a plurality of 45 degree increments of rotation of the male snap-lock rod with respect to the body upon insertion of the male snap-lock connector into the first female receptor.

According to yet another example, the snap-lock block comprises one or more male snap-lock connectors disposed about a periphery of the body.

In accordance with still another exemplary aspect, a snap-lock toy is provided comprising a snap-lock block and a snap-lock rod. The snap-lock block, for example, comprises a body, an octagonal male feature extending outwardly a first predetermined distance from a surface associated with the first end of the body, and a first female receptor generally centered inside the octagonal male feature. The snap-lock rod, for example, comprises an elongate body having a generally square cross-section, and a male snap-lock connector. The male snap-lock connector, for example, is configured to selectively matingly engage the first female receptor of the snap-lock block, wherein the octagonal male feature and first female receptor provide a plurality of 45 degree increments of rotation of the male snap-lock rod with respect to the body of the snap-lock block upon insertion of the male snap-lock connector into the first female receptor.

In one example, the snap-lock block further comprises a first end and a second end of the body disposed along an axis thereof. The body of the snap-lock block, for example, comprises a pair of cantilevered receptor wings disposed about the axis and extending approximately from the first end to the second end. The pair of cantilevered receptor wings, for example, are cantilevered from a leverage point associated with the first end and extend toward the second end. The first female receptor, for example, is defined in the first end of the body of the snap-lock block, wherein the first female receptor has a first snap diameter defined between the pair of cantilevered wings. A second female receptor, for example, is defined in the second end of the body of the snap-lock block, wherein the second female receptor has a second snap diameter defined between the pair of cantilevered wings. The second diameter, for example, differs from the first diameter, wherein a first predetermined moment is associated with the first female receptor and a second predetermined moment is associated with the second female receptor. The first predetermined moment and second predetermined moment, for example, are defined based on a predetermined insertion force associated with an insertion of a male snap-lock connector into the first female receptor and second female receptor.

In another example, the first predetermined moment is based, at least in part, on the first snap diameter, and the second predetermined moment is based, at least in part, on the second snap diameter. The predetermined insertion force, for example, is approximately equal for an insertion of the male snap-lock connector into both of the first female receptor and second female receptor.

The first predetermined moment and second predetermined moment, for example, are further based on a respective first distance from the leverage point to the first snap diameter and a second distance from the leverage point to the second snap diameter. In another example, the first predetermined moment and second predetermined moment are further based on a material composition of the pair of cantilevered receptor wings.

The snap-lock block may further comprise a generally square feature extending inwardly a second predetermined distance from the second end of the body, wherein the octagonal male feature and generally square feature are sized such that generally square feature overlaps the octagonal male feature when viewed along the axis.

The octagonal male feature and generally square feature may be configured to provide a friction fit between another octagonal male feature and another generally square feature of another snap-lock toy, wherein the another octagonal male feature is dimensioned the same as the octagonal male feature and the another generally square feature is dimensioned the same as the generally square feature.

DETAILED DESCRIPTION OF THE INVENTION

The present disclosure is directed generally toward construction toys, wherein the construction toys comprise one or more features configured to provide interconnections therebetween with a uniform force and at a plurality of angles. The construction toys of the present disclosure may utilize reusable snap-lock components and/or friction-fit components configured to enable a user to construct assemblies of various shapes and configurations.

Accordingly, the present invention will now be described with reference to the drawings, wherein like reference numerals may be used to refer to like elements throughout. It is to be understood that the description of these aspects are merely illustrative and that they should not be interpreted in a limiting sense.

In particular, the elements shown in the drawings are not necessarily to scale with each other, and the placement of various elements in the drawings is chosen to provide a clear understanding of the respective embodiment and is not to be construed as necessarily being a representation of the actual relative locations of the various components in implementations according to an embodiment of the invention. Furthermore, the features of the various embodiments and examples described herein may be combined with each other unless specifically noted otherwise.

It is also to be understood that in the following description, any direct connection or coupling between functional blocks, devices, components, circuit elements or other physical or functional units shown in the drawings or described herein could also be implemented by an indirect connection or coupling. Furthermore, it is to be appreciated that functional blocks or units shown in the drawings may be implemented as separate features in one embodiment, and may also or alternatively be fully or partially implemented in a common feature in another embodiment.

Referring now to the Figures, FIGS. 1A-1C illustrate various views of an exemplary snap-lock rod 100 in accordance with various aspects of the present disclosure. While various shapes and configurations of the snap-lock rod 100 are contemplated, the snap-lock rod in the present example takes the shape of an elongate rod 102. The snap-lock rod 100 of FIG. 1A, for example, has a generally square shape when viewed from a first end 104 (e.g., illustrated in FIG. 1B) or a second end 106 (e.g., illustrated in FIG. 1C).

In one example, the snap-lock rod 100 comprises one or more of a male snap-lock connector 108 illustrated in FIGS. 1A and 1B, and a female snap-lock connector 110 illustrated in FIGS. 1A and 1C, whereby the one or more of the male snap-lock connector and female snap-lock connector are associated with one or more of the first end 104 and second end 106 of the snap-lock rod 100. In accordance with one example, the one or more of the male snap-lock connector 108 and female snap-lock connector 110 are configured to enable selective snap-lock connections to one or more other snap-lock rods, as will be further described infra. For example, the snap-lock rod 100 may be a component of a child's construction toy, whereby the snap-lock rod is selectively interconnected to other snap-lock toys to form an endless variety of shapes, figures, or objects. In accordance with one example, the snap-lock rod 100 is comprised of a substantially rigid plastic.

The male snap-lock connector 108, for example, comprises a head 112, a neck 114, and a shoulder 116, as illustrated in FIG. 1A. In one example, one or more of the head 112, neck 114, and shoulder 116 are circular-shaped about a central axis 118. As illustrated in FIG. 1A, the head 112 extends from the neck 114 and has a widened central diameter region 120, thus defining a mushroom-shaped tip 122. In other examples, although not shown, the head 112 may be a spherical or an otherwise curvilinear shape. As illustrated in FIG. 1A, the neck 114 has a conical shape with narrowed region 124 joining with the head 112 and a widened region 126 joining with shoulder 116. The shoulder 116, as illustrated in FIG. 1B, has a generally rounded octagonal shape around its perimeter. In other examples, while not shown, the shoulder 116 may have a cylindrical shape having a smooth circular circumference, or other polygonal shape.

The female snap-lock connector 110 of FIGS. 1A and 1C, for example, has a generally hollow interior 128 and extends into a body 130 of the snap-lock rod 100. The female snap-lock connector 110, for example, is generally defined by a bifurcated engagement member 132 in the body 130, whereby the bifurcated engagement member is sized and proportioned to receive a male snap-lock connector 108 from another snap-lock rod 134, as illustrated in the non-limiting example of FIG. 2. For example, the male snap-lock connector 108 of the another snap-lock rod 134 may be inserted along the central axis 118 (e.g., illustrated by arrow 136), and may be seated in the snap-lock rod 100 as shown in FIG. 2.

As illustrated in FIGS. 3A-3B, the bifurcated engagement member 132 of the female snap-lock connector 110 comprises a first female engagement member 138A and a second female engagement member 138B separated by a slit 140. The first female engagement member 138A and a second female engagement member 138B, for example, are mirror images of one another (e.g., when viewed along the axis 118) and comprise a wall 142 having a head engagement region 144, a neck engagement region 146, and shoulder engagement region 148. In one example, the shoulder engagement region 148 is a complementary shape to, although slightly larger than, the shoulder 116 of the male snap-lock connector 108 (e.g., a generally rounded octagonal shape around its perimeter). One or more ribs 150, for example, are further defined in the body 130, whereby the one or more ribs act to support or buttress the first female engagement member 138A and second female engagement member 138B.

The one or more ribs 150 and slit 140, for example, are configured to enable the first female engagement member 138A and second female engagement member 138B to elastically or resiliently deflect as the head 112 of the male snap-lock connector 108 of FIG. 2, for example, is pushed through the neck engagement region 146 of FIGS. 3A-3B. The one or more ribs 150 and slit 140, for example, are further configured to substantially return the first female engagement member 138A and second female engagement member 138B to their original states or positions once the head 112 of male snap-lock connector 112 is lodged within the head engagement region 144 of female snap-lock connector 110, as illustrated in FIG. 2.

As the head 112 of the male snap-lock connector 108 slips into the head engagement region 144 of female snap-lock connector 110, the shoulder 116 of the male snap-lock connector mates with the shoulder engagement region 148 shown in FIG. 3B. In an example where the shoulder 116 of the male snap-lock connector 108 has an octagonal shape as illustrated in FIG. 3A, the male snap-lock connector 108 is thus generally locked into a particular orientation with respect to female snap-lock connector 110.

The orientation of the mated male snap-lock connector 108 and female snap-lock connector 110, for example, may be adjusted by twisting with a small amount of pressure about the central axis 118 of FIG. 2, thus causing the shoulder 116 of the male snap-lock connector 108 to shift with respect to the shoulder engagement region 148 of the female snap-lock connector 110. Such a shift temporarily displaces the first female engagement member 138A and a second female engagement member 138B until the shoulder 116 of the male snap-lock connector 108 to again mates with respect to the shoulder engagement region 148 of the female snap-lock connector 110 (e.g., the octagonal patterns align). The shoulder engagement region 148 of the female snap-lock connector 110, for example, generally provides a plurality of 45 degree increments of insertion of the male snap-lock connector 108.

It will be appreciated that while the shoulder 116 of the male snap-lock connector 108 and shoulder engagement region 148 of the female snap-lock connector 110 are illustrated as being generally symmetrically octagonal shapes, the present disclosure further contemplates other geometric shapes including three, four, five, and n-sided shapes which may be symmetrical or asymmetrical, whereby n is an integer value. It will be further appreciated that while particular edges have been described herein, shapes with sharp, rounded, or significantly curved edges, any shape is contemplated as falling within the scope of the present disclosure.

In the event that shoulder 116 of the male snap-lock connector 108 is circular (not shown), male snap-lock connector 108 may spin freely around the central axis 118 within female snap-lock connector 110. Further, it will be appreciated that the body 130 may further comprise one or more stiffening members 152, or other features that provide strength or stiffening of the snap-lock rod 100.

FIG. 4 illustrates an example of yet another snap-lock rod 154, whereby the yet another snap-lock rod comprises female snap-lock connectors 108 disposed at both the first end 104 and second end 106 thereof, whereby the female snap-lock connectors are configured in a manner similar to that described above. It should be noted that the present disclosure contemplates any number of female snap-lock connectors 108 on any configuration of a snap-lock toy. For example, FIG. 5 illustrates an angled snap-lock rod 156 comprising at least one female snap-lock connector 108. While not shown, various other configurations of snap-lock rods may be provided, such as a tee-shape, a cross-shape, an L-shape, or any other shape whereby at least one female snap-lock connector may be provided in the snap-lock rod. Similarly, any number of male snap-lock connectors are contemplates on any such snap-lock toy, as long as at least one female snap-lock connector is provided on said snap-lock toy.

In accordance with another exemplary aspect of the present disclosure, FIGS. 6A-6D illustrate another embodiment directed toward a snap-lock block 200. In one example, the snap-lock block 200 may be utilized in conjunction with the snap-lock rod 100 of any of FIGS. 1A-1C, 2, 3A-3B, and 4-5.

FIGS. 6A and 6C, for example, illustrate the exemplary snap-lock block 200 having a first female receptor 202 positioned at a first end 204 of the snap-lock block. FIGS. 6B and 6D, for example, illustrate the exemplary snap-lock block 200 having a second female receptor 206 positioned at a second end 208, thereof. The first female receptor 202 and second female receptor 206 generally define a double-sided female receptor 210 defined along an axis 211, as illustrated in the example shown in FIGS. 7A-7B.

As will be appreciated infra, the double-sided female receptor 210, for example, is configured to provide a similar connecting force when coupling a male snap-lock connector 212 (e.g., the male snap-lock connector 110 of the snap-lock rod 100 of FIGS. 1A-1C) in either of the first female receptor 202 at the first end 204 of the snap-lock block 200 of FIGS. 6A-6D and 7A-7B or the second female receptor 206 at the second end 208, thereof. The present disclosure thus provides a predetermined moment force for insertion of the male snap-lock connector that is defined such that the predetermined moment M is generally equal at the first end 204 and second end 208 of the double-sided female receptor 210.

In one exemplary aspect of the disclosure, the predetermined moment M is defined based, at least in part, on a first snap diameter 214 associated with the first end 204 and a second snap diameter 216 associated with the second end 208, as illustrated in cross section 218 of FIG. 7B. The first female receptor 202 and second female receptor 206, for example, are generally defined by a pair of cantilevered receptor wings 220A, 220B defined in a body 222 of the snap-lock block 200, whereby the pair of cantilevered receptor wings extend approximately from the first end 204 to the second end 208. As such, the first snap diameter 214 and second snap diameter 216 are defined by the pair of cantilevered receptor wings 220A, 220B in a rest position 223.

When the male snap-lock connector 212 (e.g., from another snap-lock block) is inserted in either of the first end 204 and second end 208 of the snap-lock block 200, the pair of cantilevered receptor wings 220A, 220B are displaced from the axis 211 based, at least in part, on an engagement of the male snap-lock connector with the respective first snap diameter 214 associated with the first end 204 or second snap diameter 216 associated with the second end 208 and a force F exerted therebetween along the axis.

The predetermined moment M, for example, may be further defined based a material composition (e.g., plastic or other resilient material) of the cantilevered receptor wings 220A, 220B, as well as a first distance 224 from a leverage point 226 (e.g., a supported position) to the first snap diameter 214 and a second distance 228 from the leverage point to the second snap diameter 216.

Accordingly, the first snap diameter 214, second snap diameter 216, first distance 220, and second distance 224 for example, are determined based on the material selection for the body 222 (including the cantilevered receptor wings 220A, 220B) and a desired predetermined insertion force F for the particular male snap-lock connector 212 to be inserted into the first female receptor 202 and second female receptor 206. The first snap diameter 214 and second snap diameter 216, for example, differ from one another based on a first moment M1 associated with the first female receptor 202 and second moment M2 associated with the second female receptor 206, whereby the first snap diameter 214 and second snap diameter 216 generally define the narrowest portion of the respective first female receptor 202 and second female receptor 206. Being different from one another, the first snap diameter 214 and second snap diameter 216, for example, are configured to compensate for the difference between the first moment M1 and second moment M2 to attain the same or nearly the same connecting force during insertion of the male snap-lock connector 212 into the respective first female receptor 202 at the first end 204 and second female receptor 206 at the second end 208. Such a uniform force is desirable in children's toys, such that the child will experience the same force in connections on either the first end 204 or second end 208.

In accordance with yet another exemplary aspect of the disclosure, the exemplary snap-lock block 200 further comprises an octagonal male feature 250 extending from a surface 252 associated with the first end 204 of the body 222 by a first predetermined distance 254, as illustrated in FIGS. 6A, 6C, and 7A-7B. The first female receptor 202, for example, is generally centered inside the octagonal male feature 250. The combination of the octagonal male feature 250 and the first female receptor 202, for example, provide connection of the snap-lock rod 100 of FIGS. 1A-1C thereto.

In one example, the octagonal male feature 250 provided in the snap-lock block 200 generally permits the snap-lock rod 100 to be inserted in 45 degree rotational increments, as will be understood upon viewing FIGS. 8-10. For example, as shown in FIGS. 8 and 9, male snap-lock connectors 212 of two snap-lock rods 256A, 256B are respectively inserted into the first female receptor 202 at the first end 204 and the second female receptor 206 at the second end 208 of the snap-lock block 200. FIG. 10 illustrates the coupling from the first end 204 of the snap-lock block 200.

In accordance with another example, as illustrated in FIGS. 6B, 6D, the snap-lock block 200 comprises a generally square feature 258 extending into the second end 208 by a second predetermined distance 260. For example, the octagonal male feature 140 and generally square feature 258 are sized such that the generally square feature overlaps the octagonal male feature when viewed along the axis 211. According to one example, the generally square feature 258 of one snap-lock block 200 is configured to selectively accept the octagonal male feature 250 of a similar snap-lock block, whereby the octagonal feature selectively connects (e.g., stacks) via friction with walls 262 shown in FIG. 7B that define the generally square feature. The square male feature 258, for example, is configured to mate with any number of octagonal male features of other snap-lock toys, whereby the interface between the octagonal male feature 250 and the generally square feature provide a plurality of 45 degree increments of rotation with respect to one another.

In accordance with another exemplary aspect, the snap-lock block 200 may comprise one or more male snap-lock connectors 212, whereby one male snap-lock connectors may be associated with a respective side 264 of the snap-lock block. For example, FIGS. 11A-11D illustrate other snap-lock blocks 270, 272, 274, 276 having a respective one, two, three, and four male snap-lock connectors 212 associated with respective sides 264 thereof. Further, the male snap-lock connector 212 of any of the snap-lock blocks 270, 272, 274, 276 of FIGS. 11A-11D may be coupled to the respective second female receptor 206 of any of said snap-lock blocks. Further strength can be attained by interconnection a variety of said snap-lock blocks.

The present disclosure contemplates interoperability with other snap-lock toys, such as those described in co-owned U.S. Pat. No. 8,651,914 and US Design Pat. No. D612435, the contents of which are herein incorporated by reference in their entireties.
